Why is Genetically Modified Yeast Fermentation Acquiring the Largest Market Share?

Genetically Modified Yeast Fermentation is anticipated to capture the maximum market share among all synthetic spider silk product type market segments, contributing 45% to the market in 2026. This is due to its scalability, stable for protein expression and works well with existing bioreactors that are used for synthesizing spider silk proteins.

Fermentation technology using yeast as the microorganism has the ability to manufacture silk proteins in bulk in an economically feasible manner without having to face problems posed by culturing spiders. Industrial biotechnology finds yeast more favorable due to its benefits in genetic engineering.

In September 2024, AMSilk GmbH, in collaboration with 21st.BIO, announced a strategic partnership to scale up the industrial production of recombinant spider silk proteins using advanced fermentation-based biomanufacturing platforms, including genetically engineered yeast expression systems.

Why does the Automotive Segment Account for the Largest Application Share?
